Physiological age, a measure up of aging

Physiological age and also chronological period are two various things. Chronological period is identified from the date of birth, and also despite what we can think, that does not reflect our “real” age. Our physiological age, likewise called biological or useful age, is the one that mirrors the real organic state the a person.

You are watching: Which measurement is a good indicator of physiological age


The physiological age of a person deserve to be greater or reduced than their chronological age, since aging is no only restricted to time, yet is in truth a complicated process with multiple causes. The evolution of aging have the right to be modulated through internal as well as external factors: genetics, diet, environment, mental health… Knowing your physiological age permits you to far better understand the life patterns that have actually an affect on aging, i m sorry in turn permits us to act as necessary to limit its effects.

Measuring aging: in the direction of a new field of metrology

Metrology is the scientific research of measurements. The metrology the aging concerns any method that permits to identify the degree and speed the aging of an individual. It can mean identifying and also quantifying biological and genetic markers, checking physics capabilities, or observing the physical signs connected to aging.


Although the metrology of aging has actually not yet got to its peak, countless techniques already enable us to determine the physiological period of an individual.



What space the different methods because that measuring aging?



Measuring aging: what is your organic age?

*

Measuring our biological age and also take continuous dispositions to avoid it, it’s a dream come true !


Part 1: measure up aging: Cartographie PhysiologiqueⓇ

*
This an approach to measure up aging and physiological period measures the many physical and also biological features that were certainly linked to the aging procedure (cholesterol levels, unipedal view test, central obesity…)


Part 2: measure aging: the eighteen mite of fight it out University

*

This an approach follows the decline of numerous organic equipment (cardiovascular, lungs, kidneys, liver, teeth, and immune system) by quantifying 18 markers for chronic diseases attached to aging. This technique was emerged by a research team from fight it out University, under the supervision of Dr. Daniel Belsky.


Part 3: DNA methylation, a promise lead towards the measure up of aging?

*
DNA methylation levels flourish with the variety of divisions a cabinet undergoes. The variety of cell departments grows through time. Therefore, measuring the methylation the DNA help to quantify aging. Treating DNA with bisulfites enables to convert non-methylated cytosines into uraciles, so the methylated cytosines can easily be identified. Us deduce a physiological period from their numbers.

Part 4: Telomeres, in ~ witnesses that the physiological age, as a device to measure aging

*
Telomeres have the right to be found at the finish of our chromosomes, and get shorter with age. Over there are numerous techniques to measure up their size (TRFs, Q-Fish, qPCR, STELA…) based upon the southern Blot principle, PCR and also in situ hybridization.
